The wrong suspects, the tip-off and the killers who got away - The Age

Theory Briefing

  • A theory emerged years later that Bongiorno killed Maria specifically to stop her from exposing him as a paedophile.
  • The case's title — wrong suspects, killers who got away — suggests the original investigation may have convicted the wrong people.
  • The long gap between the crime and the emerging theory points to how suppressed motive can reshape a cold case entirely.
  • Silencing a witness to protect a secret identity is a classic cover-up dynamic, raising questions about what investigators missed early on.
